Create a Fuchsia package repository

The ffx repository commands can create and manage Fuchsia package repositories on the host machine.

Concepts

When a Fuchsia device needs to run new software or update existing software, the device requests and downloads Fuchsia packages from the Fuchsia package server, which is a service that you can start (and stop) on the host machine. The Fuchsia package server then serves Fuchsia packages from a Fuchsia package repository configured on the host machine.

A Fuchsia package repository is mapped to a directory on the host machine. When handling requests from Fuchsia devices, the Fuchsia package server looks for Fuchsia packages in this directory and, when they're found, it serves the packages from this directory. Therefore, this directory is often the destination where you'd generate and store Fuchsia packages related to your development.

Once a new Fuchsia package repository is created, you need to register the package repository to your Fuchsia device (or devices), which permits the device to download Fuchsia packages from this package repository. Fuchsia devices can only download Fuchsia packages from their registered Fuchsia package repositories.

Lastly, you can set up the Fuchsia package server to serve from multiple Fuchsia package repositories on the same host machine, where you may dedicate each package repository for a specific purpose (for instance, to separate stable packages from experimental packages).

Create a package repository

To create a new Fuchsia package repository on your host machine, do the following:

  1. Create a new repository:

    ffx repository add-from-pm <PM_REPO_PATH> [-r <REPO_NAME>]
    

    Replace the following:

    • PM_REPO_PATH: The path to a directory where Fuchsia packages are stored.
    • REPO_NAME: A user-defined name for the new repository.
      • If this flag is not specified, the command names the new repository devhost by default.

    The example command below creates a new repository named my-repo:

    $ ffx repository add-from-pm ~/my-fuchsia-packages -r my-repo
    

    After creating a new repository, this command exits silently without output.

  2. Verify that the new repository is created:

    ffx repository list
    

    This command prints output similar to the following:

    $ ffx repository list
    +----------+------+--------------------------------------------------------+
    | NAME     | TYPE | EXTRA                                                  |
    +==========+======+========================================================+
    | my-repo* | pm   | /usr/alice/my-fuchsia-packages                         |
    +----------+------+--------------------------------------------------------+
    
  3. Set the new repository to be default:

    ffx repository default set <REPO_NAME>
    

    Replace REPO_NAME with the name of a repository.

    The example command below sets my-repo to be the default repository:

    $ ffx repository default set my-repo
    

    After setting the default repository, this command exits silently without output.

    For a Fuchsia device to stat downloading Fuchsia packages from this new repository, you need to register this repository to the device.

Register a package repository to a Fuchsia device

To enable a Fuchsia device to download packages from a Fuchsia package repository on your host machine, do the following:

  1. Enable your Fuchsia device to connect to the new repository:

    ffx target repository register [-r <REPO_NAME>] --alias fuchsia.com --alias chromium.org
    

    Replace REPO_NAME with the name of the repository that you want the Fuchsia device to connect to. If this flag is not specified, the command selects the default repository.

    The example below sets your current Fuchsia device to connect to the default repository (my-repo) at fuchsia.com:

    $ ffx target repository register --alias fuchsia.com --alias chromium.org
    

    After registering the repository, this command exits silently without output.

  2. Verify that the new repository is registered:

    ffx target repository list
    

    This command prints output similar to the following:

    $ ffx target repository list
    +---------+------------------------+
    | REPO    | TARGET                 |
    +=========+========================+
    | my-repo | fuchsia-f80f-f974-a123 |
    |         |   alias: chromium.org  |
    |         |   alias: fuchsia.com   |
    +---------+------------------------+
    

Deregister a package repository

To deregister a Fuchsia package repository from the device, run the following command:

ffx target repository deregister [-r <REPO_NAME>]

Replace REPO_NAME with the name of a registered repository. If this flag is not specified, the command selects the default repository.

The example command below deregisters the my-repo repository:

$ ffx target repository deregister -r my-repo

After deregistering the repository, this command exits silently without output.

Remove a package repository

To remove a Fuchsia package repository, run the following command:

ffx repository remove <REPO_NAME>

Replace REPO_NAME with the name of a repository.

The example command below removes the my-repo repository:

$ ffx repository remove my-repo

After removing the repository, this command exits silently without output.

Start the Fuchsia package server

To be able to serve packages from Fuchsia package repositories on your host machine, the Fuchsia package server must be running on the machine.

To start the Fuchsia package server, run the following command:

ffx repository server start

This command prints output similar to the following:

$ ffx repository server start
server is listening on [::]:8083

Stop the Fuchsia package server

To stop the Fuchsia package server, run the following command:

ffx repository server stop

This command prints output similar to the following:

$ ffx repository server stop
server stopped
